Germline Transgenesis in Ciona
2018Transgenesis is an indispensable method for elucidating the cellular and molecular mechanisms underlying biological phenomena. In Ciona, transgenic lines that have a transgene insertion in their genomes have been created. The transgenic lines are valuable because they express reporter genes in a nonmosaic manner.

Ciona intestinalis is an important model for studying the genetic and cellular basis of heart development. In this article we summarize the anatomy, physiology, and formation of the heart in developing Ciona embryos. We also review recent studies characterizing the gene network encoding Ciona cardiogenesis and how cellular processes interface with this

SL RNA Genes of the Ascidian TunicatesCiona intestinalisandCiona savignyi
Zoological Science, 2010We characterized by bioinformatics the trans-spliced leader donor RNA (SL RNA) genes of two ascidians, Ciona intestinalis and Ciona savignyi. The Ciona intestinalis genome contains approximately 670 copies of the SL RNA gene, principally on a 264-bp tandemly repeated element. Fluorescent in-situ hybridization mapped most of the repeats to a single site

Enhancer trap is a famous application of transposons. This method is useful for the creation of marker transgenic lines that express a reporter gene in tissue- or organ-specific manner, characterization of enhancers in the genome, finding novel patterns of gene expression, and mutagenesis.

Cititf1 and endoderm differentiation in Ciona intestinalis
Gene, 2002Studies on the initial formation of the endoderm have lead to the identification, mostly in Xenopus, of numerous genes relevant for the formation of this tissue during early embryogenesis (reviewed by Date, Curr. Biol. 9 (1999) R812-R815 and by Yasuo and Lemaire, Curr. Biol. 9 (1999) 869-879).

Ascidian sperm were activated and attracted to all of the surface of a whole egg. When the whole egg was separated into follicle cells, chorion and test cells, and the egg itself (naked egg), spermatozoa were activated and exhibited chemotaxis toward the vegetal pole of the naked egg.

REGENERACIJA PRI PLAŠČARJU CIONA
Pomurska obzorjaCiona intestinalis je plaščar (poddeblo Tunicata, deblo strunarji/Chordata), ki je spoznan za enega najbližjih živečih sorodnikov vretenčarjev. Vendar pa ima Ciona v osupljivem nasprotju z večino vretenčarjev, ki kažejo omejene sposobnosti regeneracije, močne regenerativne sposobnosti.

Dr. Kammerer's Ciona Experiments
Nature, 1923IN NATURE of May 12, p. 639, Dr. Kammerer wrote: “Not content with any of the previous experiments [made by himself on the inheritance of acquired characters], I carried out, before 1914, what may really be an experimentum crucis,” and Dr. Kammerer states that when the siphons of Ciona intestinalis are cut off they regenerate longer than they ...

Gene-regulatory networks in the Ciona embryos
Briefings in Functional Genomics and Proteomics, 2009Ascidians belong to the subphylum Urochordata or Tunicata, which is the sister group of the vertebrates. The simple architecture of the ascidian larva represents the basic chordate body plan. Recent analyses have shown many instances of developmental mechanisms conserved during evolution, while these studies have also revealed a much larger number of ...
